174-9557 - RS PRO RS 135 Multi Function Calibrator

RS PRO Current Loop Calibrator and Thermometer

For all current loop repair, calibration and maintenance needs RS PRO presents an easy to use solution. This loop calibrator offers grade precision for temperature measurement and calibration accuracy with a wide measurement range. Source and measure current loops simultaneously. Featuring a clear and easy to read LCD screen, this product is also user friendly and ergonomic with soft touch buttons, built in stand and easy to use settings.

Applications include calibration of 4∼20 mA panel meters, LED brightness testing and temperature calibration of instruments or panel meters for 11 types of thermocouples.
